MJTP1232C Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The MJTP1232C is an active-status tactile switch manufactured by APEM Inc., configured as a single-pole single-throw normally-open (SPST-NO) device rated for 0.05A at 12VDC. This through-hole mounted component features top actuation with an 8.00mm actuator height, 6.00mm x 6.00mm outline, and 160gf operating force. The switch delivers tactile feedback with 0.25mm travel distance and supports 100,000 mechanical cycles. Substitute parts are identified to address inventory availability, extended operating temperature ranges, or alternative sourcing requirements while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that determine functional compatibility:

Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A minimum), and voltage rating (12VDC or higher).

Mechanical Compatibility: Through-hole mounting, top actuation, PC pin termination, 6.00mm x 6.00mm outline, and actuator height within acceptable tolerance for PCB assembly.

Operational Compatibility: Operating force, switch travel characteristics, and mechanical life cycle rating of 100,000 cycles minimum.

Compliance & Reliability: ROHS3 compliance, MSL 1 rating, and active product status.

The three identified substitutes meet these criteria with the following distinctions:

• 2-1825955-2 (TE Connectivity): Maintains SPST-NO configuration and 0.05A contact rating with identical 8.00mm actuator height and 6.00mm x 6.00mm outline. Rated for 24VDC (higher voltage tolerance). Extended operating temperature range (-35°C ~ 85°C). Reduced switch travel (0.10mm). Includes grounding pin feature.

• PTS645TK70-2 LFS (C&K): Maintains SPST-NO configuration and 0.05A @ 12VDC rating with identical outline. Actuator height 7.00mm (1.00mm reduction). Increased operating force (260gf). Extended operating temperature range (-40°C ~ 85°C). Includes grounding pin feature.

• PTS645TM70-2 LFS (C&K): Maintains SPST-NO configuration and 0.05A @ 12VDC rating with identical outline and 160gf operating force. Actuator height 7.00mm (1.00mm reduction). Extended operating temperature range (-40°C ~ 85°C). Includes grounding pin feature.

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the MJTP1232C.

2-1825955-2 (TE Connectivity ALCOSWITCH): Select this substitute when applications require extended voltage tolerance (24VDC rating) or broader operating temperature range (-35°C ~ 85°C). The reduced switch travel (0.10mm) and grounding pin feature provide enhanced electrical performance in noise-sensitive circuits. Inventory availability is substantial (21,947 units).

PTS645TK70-2 LFS (C&K): Select this substitute when higher operating force (260gf) is required for applications demanding increased tactile resistance or when extended temperature range (-40°C ~ 85°C) is necessary. The 1.00mm reduction in actuator height may require PCB layout verification. Inventory availability is adequate (10,485 units).

PTS645TM70-2 LFS (C&K): Select this substitute as the closest functional equivalent when operating force and temperature range requirements match the MJTP1232C specifications. The 1.00mm actuator height reduction is the primary design consideration. This option provides the most direct replacement path with strong inventory support (6,949 units).

Frequently Asked Questions (FAQ)

Q: Can the 2-1825955-2 be used in a 12VDC circuit designed for the MJTP1232C?

A: Yes. The 2-1825955-2 is rated for 0.05A @ 24VDC, which exceeds the 12VDC requirement. The higher voltage rating ensures safe operation at lower voltages. Verify that the reduced switch travel (0.10mm versus 0.25mm) does not affect tactile feedback requirements in the application.

Q: What is the impact of the 1.00mm actuator height difference between the MJTP1232C and the C&K PTS645 series?

A: The C&K substitutes (PTS645TK70-2 LFS and PTS645TM70-2 LFS) feature 7.00mm actuator height compared to the MJTP1232C's 8.00mm. This 1.00mm reduction may affect finger ergonomics and tactile feedback perception. PCB layout and enclosure clearance must be verified to ensure the lower profile does not create mechanical interference or accessibility issues.

Q: Are all substitute parts compatible with the same PCB footprint as the MJTP1232C?

A: All substitutes share the identical 6.00mm x 6.00mm outline and PC pin termination, ensuring footprint compatibility. However, the actuator height differences (8.00mm for MJTP1232C and 2-1825955-2 versus 7.00mm for PTS645 series) may require enclosure or overlay adjustments. Verify mechanical clearance in the final assembly.

Q: Which substitute offers the widest operating temperature range?

A: Both C&K PTS645 variants (PTS645TK70-2 LFS and PTS645TM70-2 LFS) provide the widest range at -40°C ~ 85°C, compared to the MJTP1232C's -20°C ~ 70°C and the TE Connectivity 2-1825955-2's -35°C ~ 85°C. Select the C&K options for applications requiring extreme temperature performance.

Q: What is the difference between PTS645TK70-2 LFS and PTS645TM70-2 LFS?

A: The primary difference is operating force. The PTS645TK70-2 LFS requires 260gf, while the PTS645TM70-2 LFS requires 160gf (matching the MJTP1232C). Both share identical actuator height (7.00mm), outline, and temperature range. Select PTS645TM70-2 LFS for direct force compatibility; select PTS645TK70-2 LFS only if increased tactile resistance is required.

Q: Are all substitutes ROHS3 compliant and MSL 1 rated?

A: Yes. All three substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the MJTP1232C specifications. This ensures regulatory compliance and eliminates moisture-related reliability concerns across all options.
